Hi,
LOGPERIO.XLS
everybody knows that famous spreadsheet,
I added some features, made some changes,
added some information, added a graphic to view results,
all for my own private use, work is unfinished, no progress,
no idea when I shall proceed to make it nice and neat.
You may want to download from he
